Can you pick more than 1?
and i have to explain why an why not
Okay, do you have any idea which ones it might be? Hint: there's more than one
melting ice burning campfire
Alright, melting ice is correct, that is a physical change. Do you know why?
no i dont
Well, ice is just solid water, right? Frozen H2O. So basically, when you melt ice, you're just turning a solid into a liquid. Solid/liquid/gas are all a physical state of being. The chemical properties are the still same.
Now, burning a campfire, that would have to be chemical. There's one more physical one. The signs of a chemical change are a change in color, formation of a precipitate, formation of a gas, odor change and temperature change. Try again keeping this in mind
a rusty nail
Rust is definitely a chemical change. It's a chemical reaction to iron and steel reacting to water and oxygen over a long period of time.
Also, I'd actually say there are two other examples of physical properties besides a melting ice cube
well is it a brown dog
ohhh and bendable straw
Yes. Do you understand why? Bending a straw changes absolutely nothing about the chemical composition of the straw, you're simply changing its /physical/ state. Now, if you had said that the dog's color changed, that would be chemical. But since it's not, the color of the dog is just one of its physical properties
okay thank you so so so so so so so so so much
No problem :) happy to help
